SAFETY WARNINGS
Fire and explosion
Solvents and coating materials
can be highly flammable or
combustible when sprayed. ALWAYS
refer to the coating material suppliers
instructions and COSHH sheets
before using this equipment
Users must comply with all local
and national codes of practice
and insurance company
requirements governing
ventilation, fire precautions, operation
and house-keeping of working
areas
This equipment, as supplied,
is NOT suitable for use with
Halogenated Hydrocarbons.
Static Electricity can be
generated by fluid and/or air
passing through hoses, by the spraying
process and by cleaning non- conductive
parts with cloths. To prevent ignition
sources from static discharges, earth
continuity must be maintained to the
spraygun and other metallic equipment
used. It is essential to use
conductive air and/or fluid hoses.
Personal Protective
Equipment
Toxic vapours – When sprayed,
certain materials may be
poisonous, create irritation or be
otherwise harmful to health. Always read
all labels and safety data sheets for the
material before spraying and follow any
recommendations. If In Doubt,
Contact Your Material Supplier
The use of respiratory protective
equipment is recommended at all
times. The type of equipment must be
compatible with the material being
sprayed.
Always wear eye protection when
spraying or cleaning the spraygun
Gloves must be worn when
spraying or cleaning the
equipment
Training – Personnel should be given
adequate training in the safe use of
spraying equipment.
Misuse
Never aim a spraygun at any part of the
body
Never exceed the max. recommended
safe working pressure for the equipment
The fitting of non-recommended or non-
original spares may create hazards
Before cleaning or maintenance, all
pressure must be isolated and relieved
from the equipment
The product should be cleaned using a
gun washing machine. However, this
equipment should not be left inside gun
washing machines for prolonged periods
of time.
Noise Levels
The A-weighted sound level of
sprayguns may exceed 85 dB
(A) depending on the set-up being used.
Details of actual noise levels are
available on request. It is recommended
that ear protection is worn at all times
when spraying.
Operating
Spray Equipment using high pressures
may be subject to recoil forces. Under
certain circumstances, such forces could
result in repetitive strain injury to the
operator.

Installation
Important: To ensure that this equipment
reaches you in first class condition,
protective coatings have been use. Flush
the equipment through with a suitable
solvent before use.
1. Attach air hose to connector (19).
Recommended hose size 8 mm bore.
The hose must be conductive and
electrical bond from the spraygun to
earth should be checked with an
ohmeter. A resistance of less than
10
6
Ωis recommended.
2. Air supply should be filtered and
regulated.
1. Turn off air supply and relieve pressure
in the airline, or if using QD system,
disconnect from airline.
2. Empty coating material into a suitable
container and clean the gun and cup,
preferably in a gun wash machine.
3. IMPORTANT– the cup must not be
cleaned or rubbed with a dry cloth or
paper. It is possible to generate a
static charge, by rubbing, which if
discharged to an earthed object
could create an incendive spark and
cause solvent vapours to ignite. Only
use a dampened cloth or antistatic
wipes if additional cleaning is
required in a Hazardous area.
4. Remove air cap and clean. If any of the
holes in the cap are blocked with
coating material use a toothpick to
clean. Never use metal wire which could
damage the cap and produce distorted
spray patterns
5. Ensure the tip of the nozzle is clean and
free from damage. Build up of dried
paint can distort the spray pattern.
6. Lubrication – stud/screw (20,22), needle
(12) and air valve (15) should be oiled
each day.
Preventative Maintenance
Operation
1. Mix coating material to manuf acturers
instructions
2. Turn needle adjusting screw (14)
counter-clockwise until first thread
shows
3. Turn pattern valve (8) counter-clockwise
to fully open
4. Adjust inlet air pressure to give 1.6 bar
(23psi) at the gun inlet with the gun
triggered. (pressure gauge attachment
shown under Accessories is
recommended for this)
5. Test spray. If the finish is too dry reduce
airflow by reducing inlet pressure. If
finish is too wet reduce fluid flow by
turning needle screw (14) clockwise. If
atomisation is too coarse, increase inlet
air pressure. If too fine reduce inlet
pressure.
6. The pattern size can be reduced by
adjusting valve (8)
7. Hold gun perpendicular to surface being
sprayed. Arcing or tilting may result in
uneven coating.
8. The recommended spray distance is
150-200 mm (6”-8”).
9. Spray edges first. Overlap each stroke a
minimum of 50%. Move gun at a
constant speed.
10. Always turn off air supply and relieve
pressure when gun is not in use.
